How do I know what amp to get for my subs?
Find the Sub’s RMS Rating For multiple subs, multiply the number of subs by their RMS ratings for a total RMS rating. The amp you choose will have to be capable of powering 75% to 150% of the total RMS rating for the entire subwoofer system.
What is the difference between amps and subs?
A subwoofer has impedance (measured in ohms) which represents the “load” an amplifier will sense on its output. An amplifier will put out different amounts of power (watts RMS) based on the impedance load it “sees.”
Should amp be bigger than sub?
An amp need not be bigger than a sub as long as its capabilities evenly match the sub’s specifications. However, it’s always better to get an amp that puts out a bit more power than your sub, especially if it’s a passive sub. If you have an active sub, you may not even need an external amp at all.
What’s the difference between 12 and 15 subs?
15 inch subwoofers are larger and displace more air than 12 inch subwoofers do, so the 12 in will have a crisper, sharper sound than the larger ones.
How many watts should my subwoofer be?
As a general rule of thumb, it is best to go with at least 300 watts in order to get enough power for your subwoofer. You can always add more speakers if you want, but it is important that the amp matches the speaker system as well.
Do subwoofers need an amp?
Do You Need An Amplifier for Your Subwoofer? In nearly all cases, the answer is yes. Unless you have a system in your car or boat that is already powering a subwoofer, you’ll need to find an amplifier that will power your sub.
What if my amp is more powerful than my speakers?
Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.
What happens if my amp is too small?
Again, just make sure you’re not using an amplifier that’s too small for the sound level you need, because cranking a power amplifier into clipping to get more output results in distortion, which can overpower the HF driver(s) even when the amplifier is small.
